Stoke City manager Mark Hughes has admitted that Ryan Shawcross is a doubt for their trip to Manchester United on Saturday.

The centre-back has been suffering with illness this past week, and Hughes has said that he does not know if he will feature against the champions.

The Welshman said that he was "reasonably confident" of Shawcross making a recovery, but said he will have to wait before pencilling him in to his match-day squad.

"Ryan Shawcross has been ill all this week," said Hughes.

"He didn't train on Thursday and we will need to check him in the morning. I am reasonably confident that he will come through but we do have alternatives."

The Potters travel to Old Trafford on the back of last week's 0-0 draw at home to West Bromwich Albion, and the former Queens Park Rangers and Fulham boss claimed that United cannot afford a slip up against his side.

Hughes' side have not won in their last three games, but the Welshman is hopeful of having American full-back Geoff Cameron back for the game against David Moyes' men.

"Geoff has trained," said Hughes. "Hopefully he won't get a reaction."
